Application filed August 22, 1919.

T 0 all whom it may concern Be it known that we, HERMAN A. Ferrar HUSEN, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, and ARTHUR P. STRONG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Nozzles and Nozzle-Fittings, of which the following is a specification.

This invention relates to a nozzle and a fitting therefor for conduits of ash conveying or like systems.

Among the objects of our invention is to provide a fitting whereby the nozzle may be readily and easily reached from the exterior of the pipe section to which it is applied, so that the nozzle when worn may be removed and be replaced by a new one from the exterior of the pipe section and without being required to disconnect or otherwise disturb the connection of the steam supply pipes to the nozzle or the fitting. A further object of our invention is to provide a structure whereby, when the throat of the nozzle is worn through by the steam, the steam discharged from the nozzle at its throat will be allowed to escape to the atmosphere on the outside'of the pipe section through the fitting, and thus give visible signal on the outside of the pipe section that the nozzle has been worn through and needs replacement by a new one. Other and further objects of our invention will appear from the following specification, taken in connection with the accompanying drawings, in which Figure 1 is a side elevational view of an elbow section of a conduit of an ash conveying or. like system and having applied thereto a nozzle and a fitting therefor con structed in accordance with our invention;

Fig. 2 is an enlarged longitudinal, vertical sectional view of said nozzle and fitting;

Fig. 3 is a transverse vertical sectional view taken on line 3-3 of Fig. 2; and

Fig. 1 is a perspective view. of the nozzle removed from the fitting.

In the drawings, we have shown a nozzle and a fitting therefor constructed in accordance with our invention and applied to an elbow section 1 of a conduit of an ash conveying or like system. Said fitting comprises a bracket 2, made integral with or otherwise secured to the outer casing 3 of the Specification of Letters Patent.

pipe section 1 and located on the outside thereof. The bracket2is somewhat U-shaped in form and has a longitudinal web 4 spaced outward from and arranged substantially parallel to the portion of the outer casing 3 to which the bracket is secured, the web 4 being connected with and spaced outward from the casing 3 by webs 5, 5 at the ends thereof. The bracket is open at its side, as shown in Figs. 1 and 3, so that access may be readily had into the space between the bracket 2 and the outer casing 3 for the purpose of reaching the nozzle therein and for another purpose to be hereinafter mentioned. The web l is provided between its ends with a threaded hole 6 opening into the space between the bracket and the pipe section and in direct alinement with a threaded hole 7 in the outer casing 3 of said pipe section. Screwed into said hole 6 is a tubular member 8 having external screw threads throughout its length and open at both ends and provided at its upper or outer end with a flange 3, hexagonal in shape to receive a wrench or other tool for turning said tubular member. Secured to the outside of the web I in line with the hole 6 is a pipe section 10 having a flange 11 hearing against said web and secured thereto by screw bolts 12. A pipe section 13 is connected with the one 10 by a coupling member 1%, said pipe constituting a portion of the conduit by which steam is supplied to the nozzle 15.

The nozzle 15 is interposed between the tubular member 8 and the hole 7, and is provided with a threaded lower end 16 to be screwed into the threaded upper end of the tubular member 8. Adjacent such end, the nozzle 15 is provided with an outwardly extending flange 1'. to seat against the upper end of the tubular member 8 and hexagonal in shape to receive a wrench or other tool. The nozzle 15 has the shape shown in the drawings, is made of sheet metal, and has a uniform thickness throughout so that the weight and cost of construction of the nozzle is reduced to the minimum. Said nozzle is provided adjacent its lower end with a restricted throat 1S, and its upper end is flared outward and provided with an outwardly extending flange 19 having a circular outer edge to bear laterally against an annular wall 20 provided between the ends of the passage in a tubular ineml er 21 screwed into the hole the pipe section- 1;. vided' at its'outer end with a flange 22, also hexagonal in shape and serving to limit the distance that the member extends into the pipe section 1. In the particular form of elbow section shown, there is a liner section 23 located in the same and resting against the outer casing 3 and provided with an opening or hole 2% to receive the upper end of the tubular member 21 and permits steam to be injected into the, elbow section from the nozzle 15 in the direction of flow of the ash or other material therethrough.

When the nozzle 15 is in position for j'ecting steaminto the elbow or pipe section 1, the parts occupy the positions shown in Fig. 2, and it will be noted that the tubular member Ssupports' the nozzle 15 with its flange 19 bearing against the wall 20 of the member '21. As the nozzle 15 is made of sheet'metaland therefore has a relatively thin wall and will expand when heated by the steam passing therethrough, the upper flange 19 will engage tightly, against tiie wall 20- to form a steam-tight joint between the parts. The wearing action of the steam passing through the nozzle is greatest on the 'nozzle at its throat 1S, and it is at such part that the nozzle is first worn through. As the throat of the nozzle is in the space between the web a and the outer casing 3, the steam discharged from the nozzle through its worn throat escapes to the atmosphere on the outside of the pipe section through the open sides 01" the brackct'2.

As the steam escapes in clouds, it can be readily seen by workmen about the system and thus gives visible signal. from the or;- terior 01 he pipe section that the nozzle has been'worn through and needs to be removed and replaced by a new one. lVhen this happens the steam supply is turned off and access gained to the nozzle through the open sides of the bracket 2. The locknut 25, which is also hexagonal, is first loosened from its bearing against the web a, and then a wrench or other tool is engaged about the flange 9 of the tubular member 8 and the latter screwed down toward the web t until the upper end of the nozzle '15 clears the tubular member 21, as shown in Fig. 3. When the parts are in such position, a wrench or other tool is engaged with the nozzle at its base flange 1? and the nozzle unscrewed from the tubular member 8 and removed from the fitting through either one of the open sides of the bracket 2. After the worn nozzle has been removed, it may be replaced by a new one while the tubular member 8 is in its lowered position, as shown in Fig. 3, and when the new nozzle is engaged therewith, the tubular member 8 may be elevated to a position to engage the nozzle with the member 21 and the member 8 irom the outside of' Said member 21 is proprevented from further movement by the clampingof the lock-nut 25 againstthe web 4L otthe bracket. l/V hen the tubularimemher 8 is-screwed down to release the nozzle, it extends down into thepipe sections 10 and 13 and permits the nozzle to be removed therefrom without disturbing or otherwise disconnecting the said pipe sections from the bracket 2; lhus considerable labor is avoided in'removing and applying the nozzle to the fitting, and the steam pipes to the nozzle need not be disturbed or their connection with the bracket 2 be affected.

Therefore, no more labor is required then that necessary to screw down the tubular member 8 and unscrew the worn nozzle therefrom and replace it by anew one." More tied without departing from the spiritland scope of our invention.
